'TIRE-COOLING DEVICE.

SPECIFICATION forming part of Letters Patent No. 593,483, dated November 9, 1897. Application filed January 19, 1897l vSerial No. 619,797. (No inodel.)

To alllwhom it may concern:

Be it known that I, SALOMON M. MATHISEN, residing at Portland, in the county of Multnomah and State of Oregon, have invented a new and Improved Tire-Cooling Machine, of which the following is a specification.

My invention is in the nature of an improved means for cooling a tire after the same has been upset and put back on the wheel; and such invention primarily has for its object to provide a machine ofv this character of a very simple and economical construction, which can be easily manipulated, and which will eectively serve for its intended purposes.

XVith other objects in view, which will hereinafter be pointed out, the invention consists in a machine embodying the peculiar combination and novel arrangement of parts, such as Will-be rst described in detail, and then be specifically pointed out in the appended claims, reference being had to the accompanying drawings, in which- Figure 1 is a top plan view of my improvement, the platform and Wheel being held to their elevated position. Fig. 2 is a similar view, the platform and wheel being at their immersed or lowered position. Fig. 3 is a longitudinal section of the same, taken on the line 3 3 of Fig. 1. Fig. 4 is a' similar view taken on the line 4 4 of Fig. 2.

In its practical construction my improvement comprises an -immersing-tank, a platform movable vertically thereon, adapted to form a support for the wheel, and means for raising and lowering the platform to hold the wheel either in position to receive the hot tire or down in the water-tank, suitable detent devices being also employed to hold the platform to its elevated position.

Referring now to the accompanying drawings by numerals, like numerals indicating corresponding parts in all the figures, 1 indicates the immersing-tank or water-box, composed of a series of heavy timbers joined to form end members 2 and sides 3, which are braced and held water-tight by stay-bolts and nuts 4 and 5, a bottom 6, and a top crossplank 7, located at one end of the frame formed by the several timbers.

8 indicates a cross-plank or trap member 'ninged to the cross-plank 7, which is provided in Figs. 3 and 4, such top board having also secured thereto a pair of cross-bars 14, projected below the timbers 12 and 13, which have a hinged connection with the cross-bars 15, held on the bottom of the water-box, such cross-timbers 15 being hinged to the box-bottom and the bars 14 in such a manner as to fold down on the box-bottom, as shown in Fig. 4, and admit of the platform descending forwardly and vertically into the water-box. The top 11 has a central opening 11a for the passage of the wheel-hub, and at one side it has a staple 16, adapted to pass through the apertured strap 9, such strap and staple lock devices providing for the locking of the platform to its elevated position to receive and support the wheel, a suitable presser or block screw lever device 18, which engages a cross-timber 17, being provided for holding the wheel secure on the platform, as will be manifestly understood from the-drawings.

By referring now more particularly to Fig. 2, it will be observed that when the platform is at its elevated position the hinged cross-timbers will assume a vertical position, hold the top 1l in a plane with the trap or hinged member, which is swung down and forms a lock portion to hold the platform raised and also `With the end cross-piece, a continuation of the top of the machine, the staple and lock strap also serving to hold the platform from lateral movement.

The platform lO is of a length and Width somewhat less than the internal space of the' box between the sides, one end, and the front edge of the trap-piece when swung down, whereby surrounding spaces 19 are produced to provide for a free escape of steam, and also for the insertion of a lever 20, hollow at one end, as at 21, whereby it can be readily slipped onto a projecting member 22, bolted to one of the bottom hinged cross members 15, as clearly shown in Fig. 8. If desired, a lever may be used at each side of the platform, though for ordinary uses Vbut one is necessary.

The manner in which my machine is oper- IOO ated is best explained as follows: When the wheel-holding platform is raised, as shown in Fig. 3, it is held to such position by turning down the trap or hinged board 5 and securing the same to the platform-top 11 by the strap and staple connection. The wheel is then set on the platform and made fast thereto by the clamp device 18, which passes through the hub. The tire is then upset the old way by heating and while hot set onto the wheelfelly. The lock-strap is then raised and the hinged board swungI backto the position shown in Fig. 4. The operator then swings the lever forward to the position shown in Fig. 4, which causes the platform and wheel to move forward and downward under the water, it being obvious that as the entire Wheel is thus at once immersed the entire tire is cooled at once and caused to shrink on the fellyin a uniform manner, itbeing also readily apparent that the immersing operation can be eifected so quickly after the tire is set on the felly that the danger of burning the felly is reduced to a minimum. After the tire is cooled the lever 2O is swung back and the platform raised again and the wheel removed.

My invention provides a Very simple, cheap, and handy machine for blacksmith-shops, saves time in effecting the coolin g of the tire, and no burning of the felly.

To avoid a too great lever-pressure for moving the platform in the water-box, the top 11 of such platform is provided with a number of apertures 25 for the free passage of the water therethrough.

In practice the water-box is placed in the ground with the top about level with the ground surface, as shown.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, isf 1. A tire-cooling machine, consisting of a water-box, a platform of less width than the box, link connections joining the platform to the bottom of the box, adapted when adj usted in one position, to form vertical supports for the platform and when adjusted to the other position to swing the platform diagonally downward in a horizontal plane, an operating-lever projected into the box between the platform and the edge thereof, detachably secured to the link connections and a cover member laterally hinged on the top of the box to be-turned up and back to allow the platform to descend, or to be turned down to cover the water-box and laterally engage the platform to hold it raised, substantially as shown and for the purposes described.'

2. The combination with the water-boxhaving a hinged trap member at one end, and the `supporting-bars 15 hinged to the bottom of the box to swing down fiat thereon, one of such bars 15 having a projecting member 22 at one end of the platform 10, ofl a Width less than the width of the box whereby side spaces 19 are formed, a lever-handle adapted to pass through one of such spaces 19, to engage the member 22, said platform having pendent members hinged to the upper ends of the bars 15, the strap-plate 9 and the staple 6 all being arranged substantially in the manner shown and for the purposes described.

3. A tirecooling machine, consisting of a water-box, a platform consisting of a top plank and a series of cross-bars and a pair of cross-bars 14, a pair of supporting cross-bars 15 hinged to the bottom of the box to fold fiat thereon, and having a hinged connection with the bars let, said bars 15 and the platform being so arranged that when the bars l5 are raised to a vertical position the top of the platform will be in a plane with the top of the box, lever devices for swinging the bars 15 to their adjusted positions and a swinging top member hinged Yto the top of the box adapted to form a rest to hold the platform from swinging forward and downward, all being arranged substantially as shown and described.
